Description

Technical Field

[0001] This utility model relates to a floor door structure, and more particularly to a floor door structure that is linked with a double-door hoist cage. It is used for a floor door structure that links an intelligent control construction hoist with a hoist cage door, and it belongs to the field of construction lifting and transportation machinery technology. Background Technology

[0002] Construction hoists are lifting and transportation machines suitable for the construction of high-rise buildings, bridges, chimneys and other structures. They are responsible for transporting people and goods between different floors of the building. Therefore, each floor needs to have a standardized transport channel and floor doors.

[0003] Existing standards and specifications stipulate that landing doors must not be opened or closed using mechanical devices controlled by the movement of the hoist cage. Therefore, in the early days of the market, landing doors and hoist cage doors were independent of each other and unconnected. With the development and popularization of intelligent control construction hoists, the degree of automation of landing doors has also been given more attention. However, due to the height of the buildings and the large number of landing doors, if a separate power system is used to be responsible for the automatic opening of the landing doors, an additional anti-pinch system is required, which significantly increases the cost of use and reduces the guarantee of safety performance.

[0004] At this time, a floor door application technology that utilizes a cage door for linkage opening was developed. Chinese patent CN215710976U, published on February 1, 2022, discloses a utility model patent entitled "A Floor Door Structure Cooperating with a Cage." In this patent, the floor door is divided into upper and lower parts, enabling linkage opening with the cage door and effectively solving the height limitation problem of vertically opening floor doors. However, this technology suffers from poor stability during vertical opening and movement, and has too many rollers, making installation complex.

[0005] Our company's patent, published on August 9, 2024, with publication number CN221500291U, discloses a utility model patent entitled "A Floor Door Structure for Linking Construction Hoist and Cage Door". In this patent, the floor door consists of three parts, with two parts linked by steel wire ropes. The linkage rod of the floor door is supported by a door support device of the cage, achieving linkage opening with the cage door.

[0006] The above two floor door structures can only be used for scenarios where the hoist cage discharge door is a single door. For hoist cage discharge doors with a double-door structure, neither of these solutions can be used. (A single-door hoist cage discharge door means the door assembly consists of only one unit, opening directly from the bottom of the hoist cage to the top space; while a double-door hoist cage discharge door means the door assembly is divided into upper and lower units. When the door opens, the upper half moves upward and the lower half moves downward. The two halves are connected by a steel wire rope. The lower half acts as a counterweight to the upper half, offsetting some of the force required to open the door, achieving labor-saving and energy-saving effects.) When using a double-door hoist cage discharge door on the construction site, it has a unique advantage: a simple flap structure can be directly built on the lower half of the door. The movement of the lower half triggers the flap, compensating for the horizontal gap between the hoist cage and the floor. It is difficult to achieve a single-door structure for the discharge gate of the hoist cage. It can only be equipped with a separate power-driven push rod flap, which opens the flap by utilizing the time difference of the door opening. This undoubtedly increases the operating cost.

[0007] Therefore, it is particularly necessary to provide a floor door with a reasonable structural design that can be a double door structure with the cage discharge door, and can be linked and opened vertically. Utility Model Content

[0008] The purpose of this utility model is to overcome the above-mentioned deficiencies in the existing technology and provide a floor door structure that is simple and reasonable in structure design, safe and reliable, easy to operate, suitable for construction hoists with double-door discharge doors, and can be linked with the double-door discharge doors of the hoist cage.

[0009] The technical solution adopted by this utility model to solve the above problems is as follows: the floor door structure linked with the double door of the hoisting cage includes an integral door frame and door guide wheels. The integral door frame is provided with a bent plate to serve as a guide rail, and a door guide wheel is provided above the guide rail. The feature is that it also includes an upper half door, a lower half door, a pulley and a steel wire rope. The upper half door and the lower half door slide up and down along the same track plane. Both the upper half door and the lower half door have hanging rope plates, which are connected by the steel wire rope passing around the pulley.

[0010] Preferably, the present invention also includes multiple rollers, with rollers provided at the two lower corners of the upper half door and rollers provided at the two upper corners of the lower half door, and all rollers moving up and down along the guide rail.

[0011] Preferably, the present invention also includes two positioning blocks, with each side of the integral door frame equipped with a positioning block.

[0012] Preferably, the upper half of the door in this invention weighs more than the lower half.

[0013] Preferably, the upper half of the door of this invention is provided with a support plate and a buffer; the support plate is used to drive the upper half of the door to move upward; the buffer prevents the upper half of the door and the lower half of the door from being clamped and subjected to large impacts when they are closed.

[0014] Preferably, the lower half of the door of this invention is provided with an anti-derailment groove to prevent the lower half of the door from detaching from the door frame bending plate during movement.

[0015] Preferably, the door guide wheel of this invention has an anti-derailment plate to prevent the door from sliding off the track when the guide wheel fails.

[0016] Preferably, the present invention uses two pulleys, with one pulley installed on each side of the integral door frame.

[0017] Preferably, the rope hanging plate of this utility model includes an upper door rope hanging plate and a lower door rope hanging plate, which are respectively installed on the upper door and the lower door.

[0018] Compared with the prior art, this utility model has the following advantages and effects: the overall structure design is simple and reasonable, safe and reliable, the upper half door and the lower half door are on the same track plane and slide up and down, and there are rope plates on both the upper half door and the lower half door. The steel wire rope is connected by passing around the pulley, which can solve the problem of realizing the linkage between the cage door and the floor door when the cage discharge door is a double door structure.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0024] Example

[0025] See Figures 1 to 3In this embodiment, the floor door structure linked with the double-door of the hoisting cage includes an integral door frame 1, door guide wheels 2, an upper door 5, a lower door 11, pulleys 3, and steel wire ropes 4. The integral door frame 1 has a bent plate acting as a guide rail, and the door guide wheels 2 are positioned above the guide rail. The upper door 5 and the lower door 11 are on the same track plane and slide up and down. The weight of the upper door 5 is greater than the weight of the lower door 11. Figure 1 The mark L in the diagram represents the floor level L.

[0026] In this embodiment, both the upper half door 5 and the lower half door 11 have rope hanging plates, which are connected by steel wire rope 4 passing around pulley 3; the steel wire rope 4 connects the upper half door 5 and the lower half door 11 together.

[0027] The rope hanging plate includes an upper door rope hanging plate 6 and a lower door rope hanging plate 10, which are respectively installed on the upper door 5 and the lower door 11.

[0028] In this embodiment, the integral door frame 1 has bent plates on both sides. The bent edges serve as guide rails for the upper half door 5 and the lower half door 11 to slide up and down. Door guide wheels 2 are also installed above the bent plates to guide and constrain the upper half door 5 to slide upward.

[0029] In this embodiment, the door guide wheel 2 has an anti-derailment plate to prevent the door from sliding off the track when the guide wheel fails.

[0030] In this embodiment, the height of the integral door frame 1 is greater than the height of the floor door, and sufficient guiding space needs to be left to ensure that the door opening height meets the national standard. The integral door frame 1 can be installed as a whole on the building (structure), which is convenient for installation.

[0031] In this embodiment, each side of the integral door frame 1 is equipped with a positioning block 13 to prevent the upper half door 5 and the lower half door 11 from sliding down due to gravity.

[0032] In this embodiment, each side of the integral door frame 1 is equipped with a pulley 3.

[0033] In this embodiment, the door is divided into two halves, upper and lower. The upper half door 5 is equipped with rollers 7 at the bottom two corners, and the lower half door 11 is equipped with rollers 7 at the top two corners. Both can move up and down along the bending edges of the bending plates on both sides of the door frame. The upper half door 5 and the lower half door 11 are on the same track plane and move up and down. The weight of the upper half door 5 is slightly greater than the weight of the lower half door 11.

[0034] In this embodiment, the upper half door 5 is provided with a support plate 8, which is used to drive the upper half door 5 to move upward; in addition, a buffer 9 is provided to prevent the upper and lower half doors 11 from being clamped and subjected to large impacts when they are closed.

[0035] In this embodiment, the lower half door 11 is provided with anti-derailment grooves 12 on both sides to prevent the lower half door 11 from detaching from the door frame bending plate during movement.

[0036] When the cage discharge door is a double-door structure, the upper door of the cage moves upward, the lever of the upper door opens, lifting the support plate 8 on the upper half of the landing door 5 upward. The upper half of the landing door 5 moves upward, while the lower half of the landing door 11 moves downward due to gravity, ensuring the wire rope 4 is taut. This continues until the cage door opens to the required height and stops. At this point, both the lower door of the cage and the lower half of the landing door are below the horizontal plane of the cage bottom plate and the landing floor, completing the landing door opening action. When the cage door closes, the lever of the upper door disengages from the support plate 8 of the landing door, and the upper half of the landing door 5 moves downward. Because the weight of the upper half of the landing door 5 is greater than the weight of the lower half of the landing door 11, it drives the lower half of the landing door upward until the upper half falls to the positioning stop 13. The upper and lower halves of the door close, completing the landing door closing action.

[0037] Based on the above description, those skilled in the art are already able to implement it.

[0038] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components. The above description is merely illustrative of the structure of this utility model. All equivalent or simple variations made based on the structure, features, and principles described in this utility model patent concept are included within the protection scope of this utility model patent.
